LINOTYPE-MACHINE Specification of Letters Patent.

Patented June 2, 1908.

Application filed February 21, 1908. Serial No. 417,098.

To all whom it may concern:

Be it known that 1, JOHN R. Rooms, of borough of Brooklyn, county ofKings, and State of New York, have invented a new and useful Improvementin Linotype-Machines, of which the following is a specification.

This invention relates to linotype machines of the character representedin Letters Patent of the United States 67 9,481, the object of theinvention being to permit the distribution of overset or imperfectlycomposed lines of matrices without the casting of slugs therefrom.

In the machine referred to there are a series of endless inclined wiresor guides on which matrices bearing the respective characters travel.These guides converge at one point in their length in order to bring theselected matrices into line. They then con tinue in parallel lines tothe casting point, and thence upward to the rear end of the machine, sothat the composed line may be carried forward to the casting mechanismand thence rearward to the distributing point. After reaching the rearend of the machine the Wires diverge to the points from which thematrices are released-this to effect the distribution of the individualmatrices to the groups from which they are delivered. The movement ofthe composed line from the composing to the casting point, and thence tothe distributing point, is effected by a pusher finger attached to anendless chain. This finger-carrying chain was operated intermittingly insuch manner that each line was arrested at the casting position and aslug cast therefrom. This resulted in various difiiculties unnecessaryto detail. I overcome these difliculties by providing means forindependently arresting the motion of the line-carrying devices beforethe line reaches the casting position so that while the line is at restthe other mechanisms perform their movements Without casting a slug,

after which the composed line will be permitted' to pass forward fordistribution.

The essence of the invention lies in means for controlling the movementof the line independently of themovements of the other parts.

In the accompanying drawings I have represented only those parts of themachine which are immediately associated with my invention, and it'is tobe understood that as to all other parts the construction represented inthe patent above named, or any similar construction, may be employed.

Referring to the drawings, Figure 1 is a diagram illustrating thegeneral arrangement of the guide Wires and line-carrying devices inrelation to the casting mechanism. Fig. 2 is a perspective view of thecasting mechanism and the line-carrying devices in their normalpositions. Fig. 3 is a similar view with the parts in position to arrestthe matrix line before it reaches the casting position.

The guide wires for the matrices are omitted in Figs. 2 and 3 in orderthat the other parts may be exposed to view, and portions of the mainframe are broken away for the same purpose.

Referring to the drawings, A represents the main frame; B the composedline of matrices; C the mold in which the slug is cast against the lineof matrices in a manner well understood in the art, when the parts arein the relation shown in Fig. 2.

D, D, Fig. 1, are the fixed, inclined guide wires on which the matricestravel from the storage points 1, 1, in converging paths, to theassembling point, 2, thence to the casting point, 3, and finally to thedistributing point, 4, wherethe wires again diverge.

E represents the line-carrying finger acting behind the composed line ofmatrices to advance the same to the successive positions named. F is theendless chain by which this finger is carried. It follows the courseindicated by the heavy black line in Fig. 1 and by the full lines inFigs. 2 and 3, receiving intermitting movement from the driving wheel G,carried by the shaft 9, which receivesmotion 'through gears g g and 9The last named gear, 9 is mounted loosely on the shaft, H, and receivesmotion through a clutch, 1, controlled by a lever, J, which in turnreceives motion from a face cam, K, through a stud or roller, Z, on theswinging arm, L, pivoted to the lever. Whenever the face cam acts onthis roller it shifts the lever, J, disconnects the clutch, I, andpermits the line carrying chain to stop, so that the matrix lineremainsat rest. The shaft H is continuously driven and imparts motion toall the operative members of the machine in the manner explained inPatent No. 679,481, in which, however, this shaft is designated by theletter M.

The arm L and its stud, Z, stand normally in the position shown in Fig.2 in relation to the lever, J, and the face cam, K, is so shaped andtimed that the chain is automatically arrested for a limited time whenit has presented the matrix line, B, in the casting position, as shownin Fig. 2.

After the casting action, the cam permits the clutch to rengage, thechain continues its motion, and the finger will advance the matrix linefrom the casting to the distributing point.

In order to enable the operator to arrest the movement of the chain andthe line carrying finger before the line has arrived at the castingpositionto the end that the casting devices may pass idly through theirmovements, and the line then be advanced past the casting mechanismdirectly to. the distributing position-I provide the arm, L, with anextension, Z, connected by a chain, P, to one end of a lever, Z inposition to be conveniently actuated by the foot of the machineoperator.

Spring Z tends to hold the arm L and its stud, l, in the normal positionshown in Fig. 2. When, however, the foot lever is actuated, the arm L isswung forward and its stud, Z, advanced to such position that it will beacted upon by the cam K before the line carrying finger reaches thecasting point, as shown in Fig. 3, the effect being to arrest the linein the position shown. The cam will continue its action, and in duetime, after the casting devices have completed their movements, the armand lever will be released and the clutch I permitted to rengage, inorder to advance the chain and the line.

It will be observed that the essence of the invention lies in theprovision of devices controllable at the will of the operator to effectthe stoppage of the line-carrying devices independently of theassembling and casting mechanism and other moving parts; and it ismanifest to the skilled mechanic that the parts may be widely varied inform and arrangement without passing beyond the scope of the invention.

I believe it to be wholly new in a machine of the present type toprovide means by which the line carrying devices may be arrested at willwithout stopping the other parts of the mechanism, and also wholly newto provide means by which the clutch for advancing the line will beautomatically thrown out of and into action at an earlier or a laterperiod at the will of the operator.

The line controlling cam K is formed, it will be observed, on the sideface of a second cam, M, actuating a lever, m, which is connected, asheretofore, through a link, 121/, and a slide, m with the swinging jaw,m which closes behind, and supports, the line carrying finger while thelatter supports the line in the casting position, as shown in Fig. 2.

Owing to the fact that the line-controlling cam, K, and the jaw closingcam, M, are connected and turn in unison, it follows that the jaw isheld open whenever a line is prematurely arrested, and until the line iscarried past it. This is necessary in order to prevent the jaw fromclosing in advance of the matrix line in such manner as to prevent itspassage.

It will be observed that the line advancing mechanism is arrested, andthe advance of the line retarded, and that the line confining jaw iscaused to remain open without arresting the movements of the other partsof the machine. In other words, the line is stopped in advance of thecasting position, and the line confining jaw is permitted to remainopen, while all the other parts of the machine are permitted to continuetheir movements. The assembling of the next line may continue and themembers of the casting mechanism may complete their various movements inthe absence of the line without producing a cast.

Of course it will be understood that the action of the pum and thedelivery of the metal thereby wi 1 be prevented by the ordinary pumpstop devices used in all these machines-which act whenever the matrixline is absent.

In considering the operation of my mechanism, it is to be noted that theline-carrying devices are arrested automatically at a predeterminedpoint, and that the devices controllable by the operator cause theseautomatic devices to actuate at an earlier and definite point. It istherefore possible for the operator to apply his foot to the controllinglever at any time, and while continuing the pressure on the lever, toproceed with the composition of the next line, knowing that thepreceding line will be automatically arrested at the proper time. Inother words, the mechanism renders it unnecessary for the operator tosus end the composition of the second line whi e awaiting the stoppageof the preceding line, although it may be stopped in advance of thecasting position.

Having described my invention, what I claim is:

1. In a line-casting machine of the class described, means for advancingthe composed line to and beyond the casting position, means forautomatically arresting the movement of said parts when the line is inthe casting position, and means controllable by the operator at will forarresting the action of the line-advancing devices before the linereaches the casting position without arresting the action of theassembling and casting mechanisms.

2. In a line-casting machine, an endless chain rovided with aline-carrying finger, means or driving the chain, meansfor throwing itsdriving devices out of action independently of the other parts when theline reaches the casting position, and means controllable by the 0erator at Will to cause an earlier action 0 the automatic devices;whereby said devices may be caused to arrest the line sooner or later,as required.

3. In a line casting machine, the endless chain, F, and the linecarrying finger carried thereby, in combination with the chain actuatingmechanism, including a driving clutch, a cam whereby the'line isnormally arrested in the castingposition during the casting operation,and controllable means for advancmg the action of the cam, whereby theline may be arrested and held in advance of the casting position, andduring the movements of the casting parts, and thereafter advanced fordistribution.

4. In a line casting machine, the endless chain, the line-carryingfinger, and the lineconfining jaw, in combination with the cam andconnections for actuating the jaw, the cam and clutch connections fordriving the chain, and the clutch-controlling lever provided with amember movable at will to engage the cam; whereby the line may bearrested and the jaw left open until after the casting operation, andthus the line distributed without having a cast taken therefrom.

5. In a machine of the class described, the

line carrying finger, its actuating chain, the clutch and intermediatemechanism for driving the chain, the clutch controlling lever, the camto actuate said lever, the swinging arm, L, mounted on the lever tocooperate with the cam, and the-foot lever, i connected with said arm.

6. In a line casting machine, and in combination with the castingmechanism, means for advancing the composed line to and beyond saidmechanism, means for confining the line. in the casting position, meansfor automatically arresting the line in the casting position andactuating the confining devices, and means for retarding at will theaction of the line advancing and confining devices without arresting theother parts; whereby the casting mechanism is permitted to pass idlythrough its movements in the absence of the matrix line, and the latterthereafter advanced for the purpose of distribution.

In testimony whereof I hereunto set my hand this seventh day ofFebruary, 1908, in the presence of two attesting witnesses.

JOHN ROGERS.
